iTSSe TSS A D V A N C E D M A T E R I A L S & P R O C E S S E S | J U L Y / A U G U S T 2 0 2 0 6 3 iTSSe TSS on steel and cast iron containers for long-term storage of nu- clear waste in geological repository [8] . Cu was selected based on its outstanding long-term corrosion resistance in deep underground geological repository environment (Fig. 3b). Finally, CST has emerged as a potential method to manufac- ture neutron shield coating (e.g., B 4 C/Al composite) for safe transportation of UNF. The CST composite-coated plate pro- vides significant attenuation of thermal neutronwith potential applications in transportation baskets, and storage racks and casks in interim storage systems [9] . CONCLUSIONS Cold spray technology is being investigated for a variety of applications in the nuclear energy sector including, corro- sion/oxidation resistant coatings for structural components in current light water reactors (LWRs), cost-effective manufactur- ing of advanced structural materials in future reactor designs, and repair and mitigation of stress corrosion cracking in used nuclear fuel storage systems. It is expected that the applicabili- ty of cold spray technology will continue to expand to new and unique types of applications.
